[Gnuplot-info] Help on Plotting Data

[Abdol S. <so...@uw...>]

Greetings,

I have a data file in text form that contains two columns of numbers =
(please see below). I use the following command {  plot  "force.dat" =
using 1:2 title 'Column', \
                      "force.dat" using 1:3 title 'Beam'} that appears =
in  http://www.duke.edu/~hpgavin/gnuplot.html to plot the data, and  I =
get the following error message:

=20
 warning: Skipping unreadable file "TESTDATA.dat"
         warning: Skipping unreadable file "TESTDATA.dat"
         No data in plot           =20

plot "TESTDATA" using 1:2 title 'X', \
> "TESTDATA" using 1:3 t 'Y'

         warning: Skipping unreadable file "TESTDATA.TXT"
         No data in plot                    =20

Any insights as to why I am not getting graphs would be appreciated.

Best regards,
